Applications
* The LTC3221 family includes fixed 5V and 3.3V output versions plus an adjustable version. All parts operate as Burst Mode® switched capacitor voltage doublers to achieve ultralow quiescent current. The chips use a controlled current to supply the output and will survive a continuous short-circuit fr
